Snap type:

Transform

 

Description:

This Snap decrypts the binary documents that it receives on its input view using the Twofish algorithm and user-specified encryption parameters.
Note: The default security in the JRE limits the key length for encryption keys. For stronger encryption keys, you would need to manually install the Java Cryptographic Extension JARs on your JCC nodes.

  • Expected upstream Snaps:  Any Snap that produces binary data in the output view such as File Reader or Compress.
  • Expected downstream Snaps:  Any Snap that accepts binary data in the input view such as File Writer or Decompress.

 

Prerequisites:

[None]

 

Support and limitations:
  • Ultra pipelines: May work in Ultra Pipelines.
  • Spark mode: Not supported in Spark mode.

 

Account: 

This Snap uses account references created on the Accounts page of the SnapLogic Manager to handle access to this endpoint. This Snap supports a Symmetric crypto account or no account. See Binary Accounts for information on setting up this type of account.

 

Views:


InputThis Snap has exactly one binary input view.
OutputThis Snap has exactly one binary output view.
ErrorThis Snap has at most one binary error view and produces binaries in the view.

 

Settings

Label

 

Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

Password


 

The string used to generate a secret key and an initialization vector. If the Secret key property is set, the password is ignored.
Example: K1qjoeFQTr

 

Secret key


The secret key used for decryption.
Example: N0FzAAe4qtY=

 

Initialization vector


The initialization vector used for decryption. It should be in hexadecimal format and should not be used in ECB mode.
Example: 296151aacf89c87f

 

Cipher mode

Required.

The mode of operation for a block cipher.

The available options include: ECB, CBC, PCBC, CTR, CTS, CFB, CFB8, CFB16, CFB24, CFB32, CFB40, CFB48, CFB56, CFB64, OFB, OFB8, OFB16, OFB24, OFB32, OFB40, OFB48, OFB56, OFB64.

Default value: ECB

 

Encryption padding

Required.

The encryption padding. 

The available options include: PKCS5PADDING, ISO10126PADDING, NOPADDING.

Default value: PKCS5PADDING
